With Sāriputta
So I have heard.At one time the Buddha was staying near Sāvatthī in Jeta’s Grove, Anāthapiṇḍika’s monastery.
Now at that time Venerable Sāriputta was sitting not far from the Buddha, cross-legged, with his body straight, and mindfulness established right there.
The Buddha saw him meditating there.
Then, understanding this matter, on that occasion the Buddha expressed this heartfelt sentiment:
“As a rocky mountain
is unwavering and well grounded,
so when delusion ends,
a monk, like a mountain, doesn’t tremble.”
